A general object of the invention is to provide a simple, practical and very effective hub structure fora hosereel'. Another object'ofthis invention is to provide a hub assembly orunitlfor a hose reel handling'a multiplicity of hoses. j I I .Another object ofthis invention is to provide a. hosereel hub embodying relatively rotatable elements and means i011conducting 'fluidsof-different characters or grades to a plurality of hoses adapted to be wound on the reel. 4 7

Another object of this invention is to provide a hose reel hub of the character referredto in which the several fluids are' kept entirelyseparate and distinct s'o'that they cannot become commingled;

' A iurther object of this invention is to provide ahub for hose reels and the like that embodies anti-friction means for connecting the" fluid conducting hub parts for free relative rotation and further embodiessealingmeansfo-r preventing the leakage of fluid from between the sections and from one fluid duct to another. v

The various objects and features of my invention will be fully understood from the following detaileddescrip'tion-of a typical preferred form and application of the inventiony throughout which description reference is made to the accompanying drawing,in which? v Fig. lis a horizontal detailed sectional View of the reelhub assembly of the invention. Fig. 2 is an'enlarged horizontal detailed sectional view of'one end-portion of thejassembly, and Fig. 3 is an end elevation of the assembly. I I

g the invention maybe said to'comprise; generally, a body or intermediate sectionl-ll, end sections l l 'an'dfl 2, and means; l3 and I 4 for rotatablyconnecting sections H and 12,; respectively, with the sec- The hose reel hub assembly of the tion. y

The intermediate section I!) may be considered the rotating element 'o'f-t'he hub assembly. The section I is 1 an elongate cylindrical block-like part and is graduated or stepped at one'end to have a small pilot l5 and" an axially facing shoul der ii of substantial area. "A second shoulder 11 or less extent isspaced' a considerable distance inwardly fr'omthe shoulder l6; The other end I! may be of uniform external diameter. It'will be observed that the main section IU of the assembly is a simple, one-piece part.

In accordance with'the invention the section it) is ported or provided with passages forcarrying the fluid to the hoses. A central longitudinal I passage lS enters the section [0 from the outer end of its pilot l5 and extends a substantial distance through the body of the section. The passage I9 has a lateral branch extending to the exteriorofthe' section In. The branch 20 com municates with the inner end portion ofthe passage l9 and is prepared for the reception of a hose, fitting, or the like.- In the case illustrated the lateral branch 20 has a thread 2| and is en- 1 larged at its mouth portion. A second central opening 22 and extends to the exterior of the secof the section l0 has'a pilot or stem l8'of subw staritial lengthand o'f relativlysmall diameter. The pilotJ 5 and the stem 1 8 are'co axialwith the body" of; the section Ill; 1The:maj r portion of the section III betWeemthestem l8 =and'the shoulder tion Ill. The'mouthfof the branch 23 may beenlarged in diameter and provided with a thread 24 to-facilitate the connection of the hose, fittin g,'-or the like; with the section I0. The branch 24' is spaced a short distance from the branch 2] and may lie in the samel'cngitudinal plane; A third duct or passage 25 enters the endof the section ID 'at or adjacent the base of the pilot I Ba'ndextends longitudinally through the section in spaced adjacent relation to the passage [9. A lateral branch 26' communicates with the inner end ofthe passage 25 and extends radially to the pe riphery of the section Ill. The wall of the'branchi 26 may carry a thread to facilitate the connection of the related-hose or fitting with the section III. In the particular construction illustrated the mouths of the three lateral branch passages 20, 23 and 26 are in alignment and occupy a common longitudinal planeand are of the same diameter.

The' section Il may be considered a relatively stationary part of the hubassembly. The section II is in thenature of a cylindrical block and is in coaxial relation with the section Ill. The end section I I is in the form of 'a cap or cup-hav ing a central socket 21 in its inner end which 'receives 'the end portion'of the section 10 with clearance. The parts are proportioned-and re-' latedso that the inner end surface ofgthe section II is adjacent andslightly inward: of the shoulder IL The section! I isconsiderably'larger in 7 diameter than the main section In and continues sure to the opening 28 and passage I9.

Means is provided for sealing between the sections In and II to prevent the leakage of fluid with the section I Lto deliver the-fluid under prose from the opening 28 and the passage I9. 7 A socket or annular groove'29 is provided'in the section seen how the sealin ring 35 is actuated'by the fiuid'pressure handled by the groove 32 and the passage 25 and how it prevents the escape'of V fluid from between the sections lliand' l I. V The means I3 for connecting the sections Ill and I I is in'thenature of an anti-friction means connecting-the sections efor free "relative rotation. i This means includes one .or more pairs' of registering annular'grooves formed in the exterior of .Lithe section I and'the Wall of the socket 21; In

2 It is believed that the utility of the hose reel hub assembly will be readily understood from the foregoing detailed description. The. assembly provides for the separate delivery of the different kinds or grades of fluid to the individual hoses and. the sealing means of the assembly positively prevents commingling of the diiferent fluids.

The means I3. and I4. connects the three sections for free relative rotation and maintains the sections in true co-axial relation. The assembly provides for the delivery of separate fluids to a multiplicity of independent hoses and yet embodies a minimum number of simple parts.
